@amiramnoam, you sure "killed" this post.

I am always afraid using any kind of anti-malware software as I have heard earlier that they themselves act as malware pop-ups and leads to system shutdown. Recently, my system was badly infected with virus and my antivirus software was not able to recover it. Then my friend introduced me to malwarebytes software and after installation, i ran a full-scan and since then my system is performing nicely. Malwarebytes is awesome. Thanks for this post.
